Known Problems

A loud buzzing or whining when the transmission is in reverse may be caused by a regulator valve in the transmission valve body. A revised valve was released that does not resonate. Careful diagnosis should be performed because other causes can create the noise.

A cleaner/lubricant is available from Mopar for when the soft top window zippers become stiff or difficult to move. Our technicians note this product works very well when the directions are followed properly.
Water may enter the liftgate ajar switch and corrode the switch connectors. This can cause the information center to display the liftgate ajar warning, the rear wiper to be inoperative, the interior lamps to stay on, the security alarm not to set, and/or the battery to drain when the engine is off. A new liftgate ajar switch is needed and the harness connector should be repaired.
Chafed wires in the neutral position switch harness can cause an inoperative or intermittent operation of the speed (cruise) control. The harness wires need to be repaired and routed away from the throttle cable bracket on the transmission.
A short circuit in the shift interlock cable solenoid can cause various symptoms—the speedometer needle may jump or vibrate when the brakes are applied, a fuse can blow in the fuse panel, or the brake warning light may illuminate. The shift interlock cable may need to be replaced.
The outer exhaust manifold studs can break and cause exhaust leaks. The outer studs, clamps, and nuts will need to be replaced and are now being tightened to a reduced torque value (20 Nm/180 in lbs
If an air or water leak is present in the driver's side foot well, the grommet for the transmission shift cable may be missing or not seated correctly. Excessive engine noise may also be present.
Parking brake adjustments should be performed on vehicles equipped with four-wheel disc brakes at the 30,000 mile service.
If the fuel gauge is inaccurate or not working, it may because the fuel tank has bowed upward and interfered with, or damaged the sending unit (fuel level sensor). If the fuel tank has bowed, fuel tank replacement will be needed.
Due to the design of the reverse gear system in the AX-15 manual transmission, it may block shifting into reverse one out of every ten attempts. An updated reverse gear is available if the concern becomes more frequent.
Floor pan rust and corrosion typically happens where salt or mud is allowed to accumulate on the vehicle. Holes drilled in the floor can contribute to rust if the bare metal is not painted or protected with corrosion resistant coatings. Floor pan kits are available from Jeep and the aftermarket to repair rusted areas.
Child seat tether anchors are available from Chrysler and can improve the performance of child restraints. Each tether kit has all the necessary parts and detailed instructions according to our technicians.
Jeep issued a recall on some ABS equipped vehicles because seals inside the master cylinder fail. When the seals fail, a loss of pressure is detected causing the ABS hydraulic pump to cycle on more frequently or run continuously. This will lead to premature failure in the hydraulic pump. There is a lifetime warranty on the seals and the hydraulic pump motor. Normal braking will still work but brake pedal effort may increase.
